A wireless power transmission system for a robotic surgical system includes features for optical data transmission. A first component of the surgical system includes a control element, a power transmission element and an optical data transmission element; and a second component of the surgical system including a wireless power receiving element and an optical data receiving element, the second component is removably mountable to the first component. In some embodiments, a barrier such as a surgical drape and/or hermetic enclosure is positioned between the first and second components. In one example, of the components is a robotic manipulator arm and another is a powered instrument removably mountable to the manipulator arm.
